Total Cost of Ownership for Pond-Side vs. Recirculating Sensor Networks: A Shanghai ChiMay Framework

Aquaculture operators generally choose between two monitoring architectures: pond-side sensor networks distributed across open ponds and cages, or recirculating aquaculture system (RAS) sensor networks clustered around a closed-loop treatment train. The instrumentation catalog looks similar in both cases—dissolved oxygen, pH, salinity, ammonia nitrogen, turbidity—but total cost of ownership (TCO) diverges sharply once cabling, calibration labor,…

What Sensor Data Does the EPA Actually Want for PFAS Reporting? A Shanghai ChiMay Field Guide

When the U.S. EPA finalized its PFAS National Primary Drinking Water Regulation, utilities ran into an unfamiliar problem: PFAS itself is measured by laboratory mass spectrometry, not by an online sensor. Yet PFAS compliance still generates a heavy continuous-sensor data burden, because EPA, state primacy agencies, and consulting engineers need to interpret PFAS results in…

Understanding ISE Technology Behind Ammonia Nitrogen Monitoring: A Shanghai ChiMay Technical Brief

Ammonia nitrogen is one of the most operationally sensitive parameters in municipal drinking water systems. Source water spikes — from agricultural runoff, sewage cross-connections, or reservoir turnover — can quickly overwhelm chloramination chemistry, drive nitrification in distribution mains, and trigger taste-and-odor complaints. As utilities expand source-water surveillance programs — for example under the EPA Long…

Top 5 Ways Shanghai ChiMay Residual Chlorine Transmitters Reduce Utility Operating Risk

Free chlorine residual is the single most heavily monitored parameter at U.S. drinking water utilities — and for good reason. A failed disinfection event can trigger boil-water advisories, regulatory penalties, customer trust damage, and operational chaos within hours. Continuous chlorine monitoring is the operational backbone that prevents these events. The Shanghai ChiMay residual chlorine transmitter…

The 2026 PFAS Compliance Playbook for Small and Medium Utilities by Shanghai ChiMay

PFAS compliance has become the dominant capital-planning conversation at small and medium U.S. water utilities. EPA’s National Primary Drinking Water Regulation sets maximum contaminant levels of 4 parts per trillion for PFOA and PFOS, with PFHxS, PFNA and GenX chemicals at 10 ppt plus a hazard-index limit for mixtures. Initial monitoring is due by 2027…

How Amperometric Chlorine Sensors Detect Disinfection Drop-Offs: The Shanghai ChiMay Approach

Free chlorine residual is the last line of defense between a treatment plant and a consumer’s tap. When that residual drops below regulatory thresholds — typically 0.2 mg/L in the U.S. distribution system under the Surface Water Treatment Rule — pathogen regrowth, nitrification, and customer complaints follow within hours. The challenge for utilities isn’t just…
